\title{Refit a GAMLSS model}
\description{
 This function refits a GAMLSS model. It is useful when the algorithm 
 has not converged after 20 outer iteration (the default value)}
\usage{
refit(object, ...)
}

\arguments{
  \item{object}{a GAMLSS fitted model which has not converged}
  \item{\dots}{for extra arguments}
}
\details{
This function is useful when the iterations have reach the maximum value set by the code(n.cyc) of the 
\code{gamlss.control} function and the model has not converged yet
}
\value{
 Returns a GAMLSS fitted model
